Engine Gears

CTP Engine Gears are built from high grade steel and fabricated to the highest standards. They perform under the most demanding applications and environments, including marine, industrial and off-highway applications. Gears on diesel engines are used to synchronize the crankshaft and camshaft, and on some applications the fuel injection pump. In addition, diesel engines utilize various gears to transfer motion to other components such as water pumps, power take offs, hydraulic pumps and flywheel ring gears for engine starting.
